Well according to this source it looks like Space World Japan, home to Titan Max (Arrow Hyper), Zaturn (Stealth Clone), and Venus (Maurer Looper) will close after 2017 due to financial and management issues.

Space world in Kitakyushu, closed reasons for management difficulties, the end of 2017

The theme park "Space World" located in Higashida district of Yahata Higashi-ku, Kitakyushu city, was closed on the end of December 2017, it was learned at the interview of the West Japan newspaper on the 16th. Management difficulty seems to be the reason. The garden announces it on the homepage even the same afternoon. It opened in 1990 to the idle land of Nippon Steel Yawata Ironworks (now · Nippon Steel Sumikin Yahata Ironworks) and was one of the theme parks representing Kyushu, the curtain closes for more than a quarter century from the start of business It will be.

Half of all regular employees who had over 100 peopleWith a total area of ​​240 thousand square meters Yahoo! Ou Dome (Fukuoka city) Three or more zoo gardens will spend about 30 billion yen, opening as a leisure facility on the theme of the universe on April 22, 1990. Large attractions called "space science learning facilities" and "screaming machines" gained popularity, and in 1997 at the peak time, the number of visitors of 2.16 million people per year was recorded. An adult ceremony in Kitakyushu City was also held since 1998.

After that, due to intensified competition with other theme parks, customers gradually passed away, and Nippon Steel of the parent company applied for application of the civil rehabilitation law in May 2005. In July of that year, we transferred the business to Kamiomori tourism (Sapporo city), and the company has continued to operate.

In the spring of 2008, Kamori tourism lowers annual free pass of 10 4700 yen for adults by 5,000 yen or more. In order to drastically improve the profit structure, we cut all regular employees who were over 100 people in half. We have been preparing a series of nearly 2 billion yen over the winter ice rink and pool in the summer to improve the ability to attract customers. The number of visitors in fiscal year 12 was approximately 1.64 million. In recent years the number of visitors has not been disclosed.

In November this year, criticism such as "cruel" etc on the Internet plans to skate the skate link which made 5,000 fish and the like ice picked up to visitors was stopped one after another.

That actually really sucks, I hope some of their stuff gets relocated. But I feel like if the park closes, that hyper is going down with it. RIP

Honestly though, is this because of the f*cking fish? They were all dead to begin with.

It's not just fish. It was more like:

Parent Company: "So you're Early 2000's Six Flagging it down the toilet, and your idea to save yourselves was to choreograph market seafood half frozen in an ice rink? How much did that cost? You're all F*** fired. We didn't even want this park anyway." *goes back to making ski resort and hotel money.

I mean clearly as a parent company you need to drop that right off the bat. That potato just went green star hot if you are a publicly traded company and don't give a crap about rides as business model why WOULD you go through the trouble of root canaling out all the stupid to retrain and bring new competent fresh new management to slow drown on an expensive sinking ship.

Oone of two things I would HOPE (please god let this happen), is that someone picks up on the premade park and fixes it with new branding like an rct2 scenario

Or, everything but coathanger Pepsi Big One gets relocated. Too many parks need those rides and they don't come up used too often. Prolly China or Vietnam will go for them

I have a hypothesis (supported by no data) that a management shift happened somewhere and that killed the park, or it was a businessy "increase shareholder value" thing.

The park clearly survived the worst of the economic downturn that cock-punched tourism in lots of places, and the park used to have the clout to attract Nintendo. If the economy killed the park, it would have gone under a few years ago. The goddamned N64 was announced there along with many other significant Gamecube-related things. It's just bizarre because the place has never appeared to be in decline. Yes it rarely added major attractions, but did it need to?

That being said hopefully the Maurer/Schwarzkopf/whatever else (seriously like 5 companies worked on that ride) gets relocated just on general principle. I could see Zaturn appearing somewhere else since it'll share parts with many other rides and not be that risky of an investment despite being an Intamin.

Wow, sucks that its closing down. Back in 2012 I missed out several rides due being too windy. (Zaturn and Titan)

Personally I hope someone is willing to buy the park and re-open it. There were plenty of cool rides around the entire park, all space themed. (Six Flags could learn from this ) Else I'd really hope that the major rides are being relocated to different parks. I enjoyed Venus a lot! Nice and powerful ride.

This is going to be interesting since both rides are plausible additions elsewhere. Venus may have problems when they consider a lack of parts, but the Intamin definitely has enough similar rides floating around and a small enough footprint to work somewhere.
